Chapter 1

Module Overview

This chapter describes the 1734sc-IF4U and the conformally coated 1734sc-

IF4KU-1 modules. Other than the conformal coating, both modules are identical

so all information applicable to the 1734sc-IF-1 also applies to the K version.

The 1734sc-IF4U-1 module has four analog input channels that support current,

voltage, RTD, resistance, and thermocouple input types.

NOTE

For applications that require it, the 1734sc-IF4U-1 provides greater RTD

accuracy than the 1734sc-IF4U.

Section 1.6

System

Overview The module communicates to the controller via a 1734 Control Net, Device Net,

or Ethernet adapter. The module receives 5 and 24 VDC power through the bus

interface.

1.6.1 Module Power-up

At power-up, the module performs a check of its internal circuits, memory, and

basic functions. If no faults are found during power-up diagnostics, the module

status LED is turned on.

After power-up checks are complete, the module waits for valid channel

configuration data. If an invalid configuration is detected, the module will

generate a PLC fault. Once a channel is properly configured and enabled, it

continuously converts the input data to a value within the range selected for that

channel.

1.6.2 Module Operation

The 1734sc-IF4U-1 module provides four, independent, analog input channels.

Each channel includes four selectable filter settings, and can be configured for

voltage, thermocouple, current, resistance, or RTD input types.

The 1734sc-IF4U-1 module uses a 20-bit Sigma-Delta ADC (Analog to Digital

Converter) to achieve 18-bit resolution. (This may be limited to 16-bits resolution

by backplane communication.) Inputs to the ADC are first multiplexed through

analog switches, and then buffered by a precision, low offset and drift,

programmable gain amplifier. The ADC also provides the programmable current

source used in resistive measurements.

The 1734sc-IF4U-1 plug-in module communicates over its isolated CAN Bus

interface through the module backplane. The 1734 network adapter then

communicates to the PLC controller.

2-2 Chapter 2: Installation and Wiring

User’s Manual Pub. 0300316-01 Rev. C

Section 2.2

Power

Requirements

NOTE

Your 24 V external power supply for the AENT adapter supplies the same

GND used for the analog portion of the IF4U-1. If you measure a voltage

source with its negative terminal also attached to chassis GND, the module

may be susceptible to noise (especially at greater Vin values while only

one channel is attached), IF the external power supply introduces a high

level of noise between its GND and chassis GND.

To remedy this, you may try a different power supply; attach the negative

terminal of the power supply to chassis GND, or simply disconnect chassis

GND from the negative terminal of voltage source being measured.

WARNING

HAZARD OF DAMAGE to the 1734sc-IF4U-1 Module

Do NOT use a 1734-EPAC power supply. This outputs 120 VAC to the

+24 V input of the IF4U-1 module. Use a power supply that matches the

+24 V input.

The module receives power through the bus interface from the +5 VDC/+24

VDC system power supply. The maximum current drawn by the module is

shown in the table below:

5 VDC

24 VDC

15 mA (maximum)

EXPLOSION HAZARD

•Substitution of components may impair suitability for Class I,

Division 2.

•Do not replace components or disconnect equipment unless power

has been switched off or the area is known to be non-hazardous.

Touch a grounded object to discharge static potential.

•Do not connect or disconnect components unless power has been

switched off or the area is known to be non-hazardous.

•This product must be installed in an IP54 rated enclosure.

•All wiring must comply with N.E.C. article 501-4(b).

2.3.2 Prevent Electrostatic Discharge

WARNING

Electrostatic discharge can damage integrated circuits or semiconductors if

you touch analog I/O module bus connector pins or the terminal block on

the input module. Follow these guidelines when you handle the module:

•Touch a grounded object to discharge static potential.

•Wear an approved wrist-strap grounding device.

•Do not touch connectors or pins on component boards.

•Do not touch circuit components inside the module.

•If available, use a static-safe workstation.

•When not in use, keep the module in its static-shield box.

2.3.3 Remove Power

WARNING

Remove power before removing or inserting this module. When you

remove, or insert, a module with power applied, an electrical arc may

occur. An electrical arc can cause personal injury or property damage by:

•Sending an erroneous signal to your system’s field devices,

causing unintended machine motion.

•Causing an explosion in a hazardous environment.

•Electric arcing causes excessive wear to contacts on both the

module and its mating connector and may lead to premature

failure.

2.3.4 Selecting a Location

Reducing Noise

Most applications require installation in an industrial enclosure to reduce the

effects of electrical interference. Analog inputs are highly susceptible to

electrical noise. Electrical noise coupled to the analog inputs will reduce the

performance (accuracy) of the module. Group your modules to minimize adverse

effects from radiated electrical noise and heat.

2-4 Chapter 2: Installation and Wiring

User’s Manual Pub. 0300316-01 Rev. C

Consider the following conditions when selecting a location for the analog

module. Position the module:

• Away from sources of electrical noise such as hard-contact switches,

relays, and AC motor drives.

• Away from modules which generate significant radiated heat. Refer to

the module’s heat dissipation specification.

In addition, route shielded, twisted-pair, analog input wiring away from any high

voltage I/O wiring.

2.4.2 Install Mounting Base

WARNING

During panel or DIN rail mounting of all devices, be sure that all debris

(metal chips, wire strands, etc.) is kept from falling into the module.

Debris that falls into the module could cause damage when power is

applied to the module.

To install the mounting base on the DIN rail, proceed as follows:

1. Position the mounting base vertically above the installed units (adapter,

power supply or existing module).

2. Slide the mounting base down, allowing the interlocking side pieces to

engage the adjacent module or adapter.

3. Press firmly to seat the mounting base on the DIN rail. The mounting

base will snap into place.

4. To remove the mounting base from the DIN rail, remove the module, and

use a small-bladed screwdriver to rotate the base locking screw to a

vertical position. This releases the locking mechanism. Then lift straight

up to remove.

2.4.3 Install the I/O Module

The module can be installed before, or after base installation. Make sure that the

mounting base is correctly keyed before installing the module into the mounting

base. In addition, make sure the mounting base locking screw is positioned
